Q: How do I select the correct Starter Capacitor for my needs?
The majority of starter capacitors will come with specs in the same range:
Voltage – 110/125, 165, 220/250 or 330 VAC
Frequency – 50 or 60 Hz
Capacitance – 50 to 1200 uf
When replacing a starter capacitor, the same capacitance and frequency as the original capacitor must be used. You can choose a new capacitor with a voltage that is in the range of the operational voltage of the motor; a capacitor will have a marked voltage indicating peak voltage acceptable. Starter capacitors will have either black plastic or phenolic case, though this will not have any bearing on how well the capacitor will work. The starter capacitor will also have a recessed top where the connections are located.
